Description

360-degree all-dimensional full-frequency loudspeaker and vibrating diaphragm thereof

Technical Field

The utility model relates to an electroacoustic device, in particular to 360 all-round full frequency loudspeaker of degree and vibrating diaphragm thereof.

Background

As is known, a speaker is a common electronic and electrical sound generating device, and its working principle is to convert an electrical signal containing sound information into a sound signal. The speaker is an important part of the sound output end of an electronic product, and is widely applied to life, work and entertainment of people.

At present, a common speaker generally includes a magnetic circuit system, a driving system and a sound transmission system. The conventional sound transmission system generally can only transmit sound in one direction, and when sound transmission in each direction is required, a plurality of speakers need to be installed at the same time and arranged towards each sound transmission direction. The arrangement can solve the problem of simultaneous sound transmission in multiple directions, but causes mutual interference among a plurality of loudspeakers, and not only has poor synchronization effect, but also brings great noise.

In order to solve the problem of 360-degree omnibearing synchronous sound transmission of a loudspeaker, a specific representative 360-degree omnibearing loudspeaker appears in the market in recent years, such as a brand new super flagship thereof, which is introduced by a German top-level Hi-End sound brand MBL: the 360-degree sound system 101 extreme. The sound production system consists of two parts, namely a sound high-power amplifier (a driving system) and a loudspeaker system, wherein the loudspeaker system consists of a pair of 360-degree omnibearing loudspeaker groups (two identical 360-degree omnibearing loudspeaker groups) and a pair of ultra-low sound guns. Each 360-degree omni-directional speaker set, as shown in fig. 1-2, is mainly composed of a frame 1, two high-pitch 360-degree omni-directional speakers 2, two mid-pitch 360-degree omni-directional speakers 3, and two low-pitch 360-degree omni-directional speakers 4 (see fig. 1). The 360-degree omni-directional speaker uses the center of the frame 1 as a base point, one group of high, middle and low-pitch 360-degree omni-directional speakers are arranged at intervals from bottom to top in the vertical direction from the base point, the other group of high, middle and low-pitch 360-degree omni-directional speakers are arranged at intervals from top to bottom in the vertical direction from the base point (see fig. 2), and the vibrating diaphragm (no matter high, middle and low pitches) of each 360-degree omni-directional speaker is a lantern-shaped vibrating diaphragm (similar to a lantern in shape), namely, a group of bending vibrating diaphragms 14 (see fig. 3-5) are uniformly arranged around the vertical central axis of the lantern shape (see fig. 6), wherein one end of the lantern-shaped vibrating diaphragm is used as a fixed end of the speaker vibrating diaphragm, and the other end of the lantern-shaped vibrating diaphragm. The fixed end of the lantern-shaped diaphragm is fixed relative to the center post 5 (see fig. 2), and the driving end is connected with the center post 5 through the matching of the coil and the magnet (see fig. 2). The high and middle-pitch curved diaphragm 14 is made of a graphite fiber (carbon fiber) sheet, and the low-pitch curved diaphragm 14 is made of an aluminum alloy sheet. The outer part of the vibration diaphragm 14 is leaf-shaped, and reinforcing ribs 15 are arranged on the body of the vibration diaphragm 14 (see fig. 3-5). The pair of ultra-low-frequency guns consists of two groups of active (built-in power amplifiers) ultra-low-frequency arrays, wherein the left and right ultra-low-frequency arrays are square columns, and 4 ultra-low-frequency units of 12 inches are built in the ultra-low-frequency arrays.

The 360 degree omni-directional speaker described above was then considered to be the revolutionary design of the speaker! As is known, the real performance effect of the scene when listening to music in a concert hall includes direct sound, reflected sound, complex and rich overtone sound, etc., the 360-degree sounding system 101 extreme is introduced because the traditional speakers cannot create an omnidirectional sounding effect, and is difficult to generate real feeling like a scene, while the 360-degree omnidirectional speakers reproduce the live performance of a symphony orchestra in a living room, so far, the 360-degree omnidirectional speakers of the MBL are still recognized as the first in the world.

However, the above 360-degree omni-directional speaker set needs the combination of the 360-degree omni-directional speakers with different frequencies of high pitch, middle pitch and low pitch, and even needs to be equipped with a super bass sound box, and although the sound effect is very good, the design has the following disadvantages: the structure is complicated and the manufacturing cost is high.
